Abstract
Physical properties of polynorbornene and polynorbornene heated in air and in vacuo were investigated.Polynorbornene had a glass transition temperature of 41.5℃.The polymer began to oxidize in air at a temperature of about 130℃.The quantities of hydroperoxide and calbonyl groups in the polymer increased with oxidation.It was thought that the x-ray diffraction peak at 2θ≈18° corresponds to amorphous halo.This moderately sharp peak suggests that molecules in the polymer are oriented relatively with regularity.It was found that the polynorbornene is a polymer having the double bonds.
